So I mostly agree with you if assigned seating was free. The problem I've had twice is where someone had asked me to trade a paid seat for a worse one to sit with a spouse. Obviously different than a child, but it speaks to something else I hate about flying. The airline makes their problems your problems. For example: flight delayed but we can rebook you for a flight that would have been cheaper if you had just booked that one, and you have no recourse. Imagine going to a restaurant and they say they are out of steak but here is a burger, but we won't give you the difference because that's what you originally ordered. What the rule should be is airlines can't charge for seats in the back half of their airplane.
